Crabgrass Takeover in Connecticut: Soil First, Then Tall Fescue

The Core Issue

Crabgrass dominates because existing lawn is weak. Poor soil = weak grass = weed invasion. No organic crabgrass killer works (corn gluten = waste).

Real Solution

1. Remove bad soil.
2. Import quality topsoil.
3. Sod or seed tall fescue (best for CT: tough, traffic-tolerant, drought-resistant).
4. Maintain well → thick lawn = best weed prevention.

Fall Action Plan

• Improve soil now.
• Spring: pre-emergent (if not seeding) or monitor.
• Overseed thin areas annually.
